routinely considered for all people who have had their visa refused or cancelled under s 501, with conditions applied to mitigate risks as appropriate. Closed detention should only be used in exceptional circumstances where identified risks cannot be managed through less restrictive means.46 RECOMMENDATION 1: The Government should replace the current system of mandatory immigration detention with a caseby-case assessment process that takes individual circumstances into consideration. Closed detention should only be used as a last resort in circumstances where all of the following elements are present: a) detention is necessary and proportionate to an immigration purpose (for example, a brief period of immigration detention may be necessary to conduct health, security and identity checks before a visa is granted) Figure 1: Hawk compound 6.2 Infrastructure concerns Due to the changing nature of the cohort and increase in violence-related incidents at YHIDC, the two lower security compounds, Hawk and Falcon, are no longer fit for purpose. b) the person has been individually assessed as posing a risk of absconding or an unacceptable risk to the Australian community, and that risk cannot be managed in a less restrictive way c) the necessity for continued detention is subject to periodic re‑evaluation and judicial review, and d) the duration of detention is subject to a maximum time limit. Each of these compounds can house up to 150 people and consist of 20 transportable units laid out in a grid. The Commission considers that the number of people housed in this layout is too difficult to manage safely, endangering the people detained and centre staff. The number of people within these compounds also makes it relatively easy for drug networks to be developed (see drug infiltration section).
